State which of the following ordered pairs is a function. Set A: (-1, 0), (-2, 1), (4, 3), (3, 4) Set B: (1, 4), (2, 3), (3, 2),
liubo4ka [24]
Sets A and B are both functions because they all have different x values. Set C is not a function because it repeats the x value of 2 and gives it two different y values.
In order to determine the correct answer, it would be helpful to set up equations. We do as follows:
Let x = students
y = adults
x + y = 215
.50x + 2y = 250
SOlving simultaneously, we have:
x = 120 students
y = 95 adults
Hope this answers the question. Have a nice day.
fomular you say :speed =distance taveled divide by time traveled .......hope this will help
To find the ratio, you Will need to find the ratio of the patio, and the ratio of the scale version of the patio.
16 feet x 20 feet = 320 ft.²
(16/4 = 4 in)/(20/4= 5 in)
4 inches x 5 inches = 20 in.²
320 ft.² / 20 in.² = 16 ft.² / 1 square inch
